الإجراء التجريبي
10 g of the dehydrocavidine-dehydroapocavidine composition obtained from the above step is mixed with 40 g of the aluminum oxide, and are then added to the top of an aluminum oxide column, and a gradient elution is employed with a solvent system of petroleum ether: ethyl acetate (1:8˜1:15) accompanied by TLC tracking. The eluate containing dehydrocavidine is combined and then is concentrated by decompression to constant weight, resulting in a 1.3 g dehydrocavidine compound and a 1.9 g dehydroapocavidine compound respectively.
